AIn order tofplace the extension in position -on the drag or the cope theecorresponding 'members of the extensionmay be assembled at the sameV time with thelmembers'of the drag or cope, or the extension may bekap-k plied to the'lask after, the flask is already I assembled. In case the' flask is already assembled 'the' separate members of the extension are placed With the Vangular offset por tion over the respective members of the part of the tlask to'Which theyfare appliedand when tvvof adjacent members are in position they may be securedtogether at the corners,

thek last piece slidingy easily into position inV the same manner or'the reason that fno aliningv pins' andy perforations are provided in connection'ivith themembers of the exten sion. VVhenthe extension is in position the extremities vare locked togetherand the'ex- '1.` In aQmolders 'iask,*-'the Y with separablefside members and separable ltension is held firmly in position by means of the angular `olset extensions Qaso that thek depth of the flask is increased the amount of the extension. vThe engagementojll the extension 24 is vsullicient to prevent the disengag'ement ofthe vextensionfrom the part of lthe flasktowvhich it is applied, even though that part is lifted fromv the extension and separated.

there is no tendency forthe partsy to become' One of the'great advantages ofthis con-- struction is that byl having a :fewl sides and end members f of .diierent lengths a great many'ditferent sizes of flaskscan be obtained by simply using the diiierent lengths' of sides and` ends` in pairs'interchangeably'.V

What I. claim is:

combination end members, of slotted lugs at an angle to the'Y members at their extremities andpwith the slots open from the outside and an a1in- I ing block piv'o'ted lin the slotl of the extremity 'and adaptedto engage the sides of the slot r of the abuttingmember Vfor alining them laterally with respect to eachother'and `for binding them releasably together.

`3.-In` a molders'ilask, the combination vvith'separable side members and end membersfhafving beveledj extremities. withl abutting'slotted lugsjat an angle to the members, andianakalining block pivotally mounted in the Vslot of one member and` adapted to engage in the slo'tof the other' member for alin-Y ingfboth of lathe members, .and'astening means in connection with the alining block l for holding the members releasably together. al.' In 'ab molders ilask, the combination vwith side members and end members With corresponding"y beveledlextremities, slotted projections at an angle'to the members at ythel ends of the members,an alining block pivotally mounted: in oneV ofk the members and adapted to engage the sides of the slot of vthe other member,l and avfastening device comprising a threaded pin projecting from the aliningblock and a nut adjustable-on the pin to*y engage the said othermember 'to hold it in position with respect tothe first named'member. v Y l 5.v In a molders ilask, the combination with separable side members and end mem# bers, of means for alining the said members withl respect to each other, and means embodying slotted lugs vat'the ends of thefmem bers Withthe slots disposed at an angle to the members,.tl ieislots being side by side VandV registering when the members' are at right angles andthe slots being open Vfrom the Vv`outside of the flask. e

'6; In a molders flask, the combination Vwith separable side membersand end members,'ofvmeans*for alining the members with respectto each ot-herat their lends, means for binding the members releasably together at the ends, said means Vcomprising slotted pro* jections at an angle tothe members, an additional alining member lin connection with' the projection 'offone of the members yadapted to engage Vthesides of the'slot'of the other? member, and Vmeans inconnection With the additional 1alinin'g member for binding the side and end members releasably together at their extremity. A

7. In a molders flask, the combination with separable side members and end Ymembers,ot means for alining them v'ith'respect to eachother at their extremities, and additional means for alining them at their extreinities'embodying open'slots and a `member pivotedin the slot oiv one member toenvgage'th'e sides of the slotfof the 'othervmember forbinding the members releasably together. Y' n 8. In a molders flask, the combination fWith separable/side membersV andl end membersjhaving beveled extremities, 'ot alining with alining perforations to engage the pins, slottedy projections at the extremities of the member adapted to register With each other, the slot being substantially at the same angle to both of the adjacent members, an Valin'ing blockpivotally mounted iny the slotv of one member and adapted to engage the slot of the other member and to fassist in alining fit vWith'the 'iirst'membeny a threaded pin in connection with the blockfandA Winged' nut vpins at the extremities of one pair of members,'the vother pair ot' members being `formed 120 adjustable on the threaded pin to bindthe members releasably together at the extremities. f 49. The combination With a molders flask, of an extension therefor comprising sep arable pieces adapted to engage the inside edge of the flask, and means to bind the separable pieces together thereby locking the extension in place on the flask.`

l0. The combination With a molders flask, of a removable extension therefor comprising members formed With angnlar eXtensions adapted to engage insidey of the flask, and means releasably to bind the separable members together at their extremities thereby locking the projections ofy the extension in engagement with the flask.

ll. The combination With a molders flask,

' the inner edge of Which is inclined inwardly,

of an extension therefor comprising separable members with an angular extensiony prising separable side and end members `corresponding in length to the sides and ends of the flask, an angular projection `of the side and' endniembers adapted to engage the side and end members of the flask, lugsat the extremitiesy of the members of the leX- inside` of the edges of the flask, and` means to bind the separable members of thel eX- tension together whereby they `are held in fixed position with respect to the flask.

14;. The combination with a molderls flask, of edges inclined inwardly, of an extension therefor comprisingseparable side members and end members, the separable side and end members having offset angular projections terminating short of the ends of the members/and Vadapted to yengage the inner edge of the flask, and means to secure sep-` arable members of' the extension together:v 55

atgtheir extremities and to bind thel eXtension in place on the ask.

15. In a molders flask, the combination with separable side members and end members with the edges of the members inclined inwardly, one pair of members being formedr aiiadditional alining means, a threaded` pin Yin connection with the blockand a thumb screiv adj iistable on the pin to bind the block in the slot and to hold ythe members to-y gether, an extension comprising separable side members and end members with an angular offset yextension less in length than the said members adapted to engage the in-' side face ofthe edge ofthe flask andto clear thealiningpins at'the extremities, and"` ,i y means to secure the members of' the` eXten-.y sion together at the corners and to bind thev extension flask.`

16. Ina molders flask, the combination with separate side members and end inembers having alining slots at the ends extendiing at ythe same angle to each member, oneV of the members at each junction being provided With'alining pins and the other With alining perforations corresponding thereto and an alining block mounted in the slot of one member at each junction movable to engage in the slot of the other member at the junction, andk means to bind the block Vin a u a n y `in position With respect to the position in the slots of theadj acent members.
